IMPROVEMENT IN CUSPADORES.

Specification f01miilg pzut of Letters Patent N0. 209,337, dated Octobe1 29, 1878; applieaoion filed July 27, 1878.

T0 all whom z't may concern:

Be it known that I, JAMES H. FERRISS, of the city of'lroy, county of Rensselaer, und Stute 0f New York, have invented zunew und useful Improvement in Spittoons, and'0f Wlii0l1 tl1e the vessel, a gravitating means t0 restore the latter to its positiou upon its base when it has been tilted 01 tipped.

My invention cousists in mmngiug a. horizontal diaphragm plate withiu a spittoon which has zu dished 01 rounded botton1 01 base, u trumpet-fonned und fiaring 1:0p, und an intermediate horizontally-contractecl zone, wioh the diaphragm-plate pla.ced between the cout-racted zone and base, und hzwing a. central opening conuecting the tw0 parts 0f the V68- se1 divided by the diaphmgm, and also side openings formed in the diaphragm-plate a1: 0r near where it joins the inside Wall 0f the spittoon.

In the accompauying dmwing obere are two k figures illustrating my invention, und like letters designa-te l1e sa-1ne arts in both of them.

Figure l sh0ws a view, in perspective, 0f a spittoon 01 cuspadore with my invention applied, and in which the osition 0f tl1e diaphragm-plate is designated by mezms 0f a dotted 1ine. Fig. 2 illustrates a. vertieal section of the same device, taken through the cente1.

The various parts 0f ehe deviee t0 which my improvement is added, as well zus the combined improvement, are designated by 16cterreference as follows: 'Ihe trumped-shaped und fiaring top through which liquids are injected or voided into th'e spittoon is designated m; (l. The base hzwing a dished form, upon. whieh the vessel rests, und which contains tl1e fluids voided into it, is illustrated ab B. The horizontally-contracted z0ne between the t0p und base is designated ab A A, produced by the approaehing lines 0f form designated ab m und n. The diaphragm-plate is shown a1: S S, und as hzwing the central opening O, Witli the smaller side openiugs y y, und when applied pro'ducing tl1e conneeted spaces b und d. The dia-phmgm-plate is shown as raised upward toward the eenoral opening, so that when liquids are voided 0r injeoted. into the opening a, whieh do notpass through the opening O, they will run down to ehe sidles of the plate und pass int0 t-he lower cham1ber, d, through the openings y y.

As ordina.rily constructed, the form 0f spittoon 01 cuspadore deseribed und. shown will, without the improvement of the diaphragnuplate, retaiu the liquid contents when turned upou it side; but, when suddenly tilted o1 tipped over upon its side by being ruu against, il: has a tendeuoy to slop over 01 t0 jet upward tl1e liquid which it eontains. This difficulty is enoirely removed by the addition of the diaphragmplate, und this furol1er adva-ntage con1es from its application. When the vessel is constructed witl1out the diaphragm und turnecl upon its side, the coutained liquid can have but little gravita.ting tendeucy to right tl1e vessel f0r the two inclined surfaces 0f the side hold, and equilibriate the gravitating forge 0f the liquid. When tl1e diaphragmplate is used, then the liquid is wholly held against the ba.se curve, und produces u gravitatiug force t0 restore the vessel to itts ba'se.

I am well awa.re that the forma of the auspadore 0r spittoou shown und desuribed is n0t:

new, und tha.t my invention only exists as an improvemeut applied to und combined With it.

While I have described und illustrated my invention zus applied to one kind 0f cuspa.dore 01 spittoon, I do 1100 desire 1:0 limit its application to the precise furm shown, but desire to make it an essential elemeni: of my invention that ehe vessel shall eontain the equivulent form of dishing base und eonnected ex panded open top.

Having tl1us clescribed 1ny invention, wha.t I claim, und desire t0 secure by Letters Patent, is-

In a spittoon 01 cuspadore having a rounded 01 dish-fornued base und an open flaring t0p, und armnged between the bottom of the flaring top und the base, tl1e diaphragm-plate S, havin g ehe cenoral opening O, sicle apertures g y, aud forming, Wibh the upper zum]. lower curved WEL11S 0f the dish-formed base,- the 0011- nected inelosures b a-nd d, as shown und as deseribed.

Signed ab Tr0y this 23d day of J uly, 1878.
